Fred and Kim Kagan have produced a report arguing for an additional 40,000 to 45,000 U.S. troops in Afghanistan in 2010. You can read their report here. Fred Kagan explains in a press release: "The report illustrates where U.S., NATO, and Afghan forces are now and where additional forces are needed to accomplish the mission. It links the U.S. force requirements to the growth of the Afghan National Security Forces on an accelerated timeline. It explains the methodology for assessing the adequacy of a proposed force-level. This product, and our recommendations and assessments, are entirely our own-they do not necessarily reflect the views of General McChrystal or anyone else."
